I wish the slaadi were all the same size - would make it easier for sure
(at least the grey and death slaadi seem the same size)...
Also, I noticed that death slaadi colors are not specified in the Fiend Folio... So far we have (true forms):
Red slaad (red, 8')
Green slaad (green, 7')
Blue slaad (blue, 10')
Grey slaad (gray, 6')
Death slaad (???, 6')
Ssendam (golden, ?')
Ygorl (black, 15')
Considering this, the only colors left over are white, yellow, orange, purple, and brown
As yellow and orange are too much like gold, that leaves us with white, purple, and brown - of these, white seems the most "primary," so I guess I would make 'em white... (Also, I guess I would make Ssendam's true form the same size as that of Ygorl.)
